The levels of organization in ecology are a way of studying the living beings where the categories are defined by the relationship that living beings have.
From smallest to largest they are the following:
• Individual,, a single living being.
,
• Population,, a group of individuals of the same species that live in the same area at the same time.
,
• Community,, which includes the populations of different species that live in the same area.
,
• Ecosystem,, the living and not living elements in an area.
,
• Biomes, are big regions characterized by their climate, flora, fauna, and soil type.
,
• Biosphere,, all the parts of Earth where life is found.
Of the options, the last one (individual, populations, community, ecosystem, biome) it's the right answer.
